The artificial intelligence boom promised marketers infinite scale and hyper-personalization. Instead, it appears to be generating a wave of consumer exhaustion. According to a new Gartner survey, 49% of U.S. consumers agree that GenAI has actively worsened the quality of AI-generated content.
As brands use these tools to flood channels with automated messaging, they are inadvertently fostering an environment of AI-driven content skepticism. For marketing leaders, the challenge is no longer about generating enough content to fill a calendar. It is about preventing severe marketing fatigue before audiences tune out entirely.

The Volume vs. Value Disconnect
The Gartner survey, which polled 307 U.S. consumers, was presented at the Gartner Marketing Symposium/Xpo taking place June 8 to 10 in Denver. The findings paint a picture of an audience overwhelmed by digital noise but starved for meaning. The data shows that the frustration is even higher among younger demographics, with 57% of Gen Z and millennials agreeing that AI has degraded the media they consume.
Kate Muhl, VP Analyst in the Gartner Marketing practice explained:
“AI-generated content is increasing the volume of media that consumers encounter, but not necessarily the value”
She added that “in a more skeptical media environment, brands need to be more recognizable, more credible and more intentional about the contexts in which they appear.”
This relentless volume is colliding with a highly distracted consumer base. The Gartner survey found that 59% of U.S. consumers prefer to multitask across media, such as watching TV while texting or browsing the internet, rather than focusing on one activity.
Muhl highlighted what this means for marketers, stating:
“Consumer screen time may be abundant, but consumer attention is not”
Diving in further, she shared that “for marketers, the goal is no longer simply to buy reach or chase impressions. Media strategy must compete for scarce attention and create brand meaning quickly enough to survive fragmented, fast-moving environments.”
AI is Changing Consumer Search Behavior
Beyond just content consumption, the Gartner data reveals that AI is fundamentally altering how consumers look for products. A separate Gartner survey of 328 U.S. consumers found that AI is shifting search habits. Twenty percent of consumers say their search inputs are more specific because of AI, 19% phrase search inputs as questions more frequently, and 17% rely on AI summaries to get product information.
“AI is changing the way consumers connect with content and where consumer attention lives,” said Muhl. “CMOs should not treat AI as a replacement for media fundamentals. The brands that win will be those that understand where attention is gathering, how trust is being formed and what kinds of experiences consumers want to remember.”

The Operational Cause of Marketing Fatigue
The Gartner data clearly outlines the consumer reaction to AI content. The operational reality of why this is happening comes down to how brands are deploying the technology. In a recent CX Today interview exploring how brands can build trust in an AI driven world, Robin Emiliani, Co-Founder and Chief Growth Officer at Catalyst Marketing, provided context on why consumers are rejecting this new wave of content.
Emiliani argued that consumers are not rejecting marketing itself. They are rejecting irrelevance. She described AI as a multiplier that improves strong strategies but accelerates weak ones.
“If your strategy is broken, it actually makes it worse faster,” Emiliani warned. “Bad targeting at scale, everyone gets irrelevant spam, unfortunately. And with automated cadences, relentless volume with no human oversight is really going to drive a lot of unsubscribes. AI makes it easier to send more messages without asking if you should.”
As AI driven content skepticism rises, Emiliani predicted that the ability to generate personalized content will soon be commoditized. The true differentiator will be how a brand respects consumer boundaries. She stated:
“I think restraint is actually going to become a brand differentiator in this world where we can create marketing at scale”
Look ahead, she highlighted “in a world of AI-generated content, I think that the scarcest resource is attention and trust. Brands that earn it and then protect it are going to be the ones that win.”
Final Takeaway
The Gartner findings serve as a stark warning to CMOs.
Using AI to simply increase output is a losing strategy. When nearly half of consumers believe AI is degrading the quality of the media they consume, brands must pivot from volume to relevance.
Combating marketing fatigue requires human oversight, clean data, and a commitment to sending one highly relevant message rather than ten mediocre, AI-generated ones. In the age of infinite content, trust and restraint are the only ways to cut through the noise.
FAQs
What is AI-driven content skepticism?
AI-driven content skepticism refers to the growing consumer distrust of digital media, fueled by the mass proliferation of generic, low-quality, or inaccurate content generated by artificial intelligence. Consumers are becoming increasingly wary of brand messaging that feels automated or lacks genuine human insight.
Why do consumers think AI-generated content quality is getting worse?
According to Gartner, 49% of consumers, and 57% of Gen Z and millennials, believe AI-generated content quality is declining because AI has drastically increased the volume of media without increasing its value. Consumers are overwhelmed by generic content that lacks context, relevance, and human empathy.
How does AI contribute to marketing fatigue?
While AI can improve personalization, it often contributes to marketing fatigue when brands use it to scale bad habits. If a brand has poor data or a flawed strategy, AI allows them to send irrelevant, poorly timed, or overly frequent messages to millions of consumers instantly, leading to high unsubscribe rates and brand alienation.
How is AI changing consumer search habits?
Gartner data shows that consumers are adapting their search behaviors due to AI. Twenty percent of consumers are using more specific search inputs, 19% are phrasing searches as questions, and 17% are relying directly on AI summaries to find product information rather than scrolling through traditional search results.
How should CMOs adjust their media strategy for AI?
CMOs should not treat AI as a replacement for marketing fundamentals. Instead of using AI to maximize reach and impressions, leaders should use it to optimize timing and relevance. Establishing guardrails, such as frequency caps, easy opt-outs, and mandatory human oversight, ensures AI enhances the strategy rather than just amplifying the noise.
